php采集文章图片不显示怎么办？
php curl采集百度搜寻结果图片不显示问题的解决方法
1.根据关键字采集百度搜寻结果
根据关键字采集百度搜寻结果，可以使用curl实现，代码如下：
<?php
function docurl($url, $data=array(), $header=array(), $timeout=30){
$ch = curl_init();
curl_setopt($ch, curlopt_url, $url);
curl_setopt($ch, curlopt_httpheader, $header);
curl_setopt($ch, curlopt_returntransfer, true);
curl_setopt($ch, curlopt_followlocation, true);
curl_setopt($ch, curlopt_timeout, $timeout);
$response = curl_exec($ch);
if($error=curl_error($ch)){
die($error);
}
curl_close($ch);
return $response;
}
$wd = '仙剑奇侠传';
$url = 'http://www.baidu.com/s?wd='.urlencode($wd);
$data = array();
$header = array();
$response = docurl($url, $data, $header, 5);
echo $response;
?>
输出后发现有部分图片不能显示
2.采集后的图片不显示原因分析
直接在百度中搜寻，页面是可以显示图片的。使用firebug查看图片路径，发现采集的图片域名与在百度搜寻的图片域名不同。
采集返回的图片域名 t11.baidu.com
正常搜寻的图片域名 ss1.baidu.com
查看采集与正常搜寻的html，发现有个域名转换的js是不一样的
采集
var list = {
graph.baidu.com: http://graph.baidu.com,
t1.baidu.com:http://t1.baidu.com,
t2.baidu.com:http://t2.baidu.com,
t3.baidu.com:http://t3.baidu.com,
t10.baidu.com:http://t10.baidu.com,
t11.baidu.com:http://t11.baidu.com,
t12.baidu.com:http://t12.baidu.com,
i7.baidu.com:http://i7.baidu.com,
i8.baidu.com:http://i8.baidu.com,
i9.baidu.com:http://i9.baidu.com,
};
正常搜寻
var list = {
graph.baidu.com: https://sp0.baidu.com/-ayhfd0a2gu2pmbgoy3k,
t1.baidu.com:https://ss0.baidu.com/6on1bjeh1bf3odcf,
t2.baidu.com:https://ss1.baidu.com/6oz1bjeh1bf3odcf,
t3.baidu.com:https://ss2.baidu.com/6ov1bjeh1bf3odcf,
t10.baidu.com:https://ss0.baidu.com/6onwsjip0qiz8tyhnq,
t11.baidu.com:https://ss1.baidu.com/6onxsjip0qiz8tyhnq,
t12.baidu.com:https://ss2.baidu.com/6onysjip0qiz8tyhnq,
i7.baidu.com:https://ss0.baidu.com/73f1bjeh1bf3odcf,
i8.baidu.com:https://ss0.baidu.com/73x1bjeh1bf3odcf,
i9.baidu.com:https://ss0.baidu.com/73t1bjeh1bf3odcf,
};
因此可以断定是，百度根据来源地址、ip、header等参数，判断如果是采集的，则返回不同的js。
3.采集后图片不显示的解决方法
把采集到的html，根据定义的域名做一次批量转换即可。
<?php
function docurl($url, $data=array(), $header=array(), $timeout=30){
$ch = curl_init();
curl_setopt($ch, curlopt_url, $url);
curl_setopt($ch, curlopt_httpheader, $header);
curl_setopt($ch, curlopt_returntransfer, true);
curl_setopt($ch, curlopt_followlocation, true);
curl_setopt($ch, curlopt_timeout, $timeout);
$response = curl_exec($ch);
if($error=curl_error($ch)){
die($error);
}
curl_close($ch);
return $response;
}
// 域名转换
function cdomain($str){
$baidu_domain = '{

}';
$domain = json_decode($baidu_domain, true);
foreach($domain as $k=>$v){
$str = str_replace($k, $v, $str);
}
return $str;
}
$wd = '仙剑奇侠传';
$url = 'http://www.baidu.com/s?wd='.urlencode($wd);
$data = array();
$header = array();
$response = docurl($url, $data, $header, 5);
echo cdomain($response); // 调用域名转换
?>
增加域名转换后，所有的图片都可以正常显示。
